Tip: how to add a 'sort' option to list page

Hi All
I was trying to do something else (see other post) by cutting and pasting code, and accidentally added a sort option to my list page. I know next to nothing about asp, but this worked for me, and I thought someone may find it useful to adapt

.

The field sorted on is called 'PropertyName'. I just pasted this code above the main data table. There my be some superfluous code here as well.
<a href="tblProperty_list.asp" onClick="java script:

document.forms.frmAdmin.action.value = 'OrderBy';

document.forms.frmAdmin.orderby.value = '<%=Replace("PropertyName","'","\'")%>';

document.forms.frmAdmin.submit(); return false; "><%=Label("Sort on Property Name")%>

</a>
